ELYON'S TRUTH?

Hello friends, where can we fine full truth? in modern institutions/or by Elyon himself? the Seer Jeremiah said we should not trust the religious scribes who writes with the lying pen, nor the prophets who prophesy falsely, (Chap,8;8, and Jeremiah,23;9) Is this Neoplatonism Monophisite Christian teachings again vs Yeshua's Apostles/Montonist truth? Yeshua said at his return many would walk in the broad way of death. (JRSL-UCYG)
